See the DC Database for Character Appearances and Plot Synopsis related to DC comics


  • Professor Emmett Vale's first name is not provided in this story. In the Post-Crisis introduction of the character, Vale's first name is identified as Emmett.[1]
  • This issue presents the first appearance of the Silver Age Supergirl, Kara Zor-El. Kara is not to be confused with the magical entity Super-Girl who predates Kara's perennial appearance by nearly one year.[2]
  • This issue is the first appearance of Supergirl's parents Zor-El and Allura In-Ze (Allura is not referenced by name in this issue). Both characters appear in flashback only. Their first actual appearance takes place in Action Comics #309.
  • This issue is the first and only appearance of John Corben as Metallo. The role of Metallo is later assumed by his brother, Roger who attempts to avenge John's death by killing Superman.[3]


  • John Corben's Metallo character is resurrected for the Post-Crisis environment. Similar to his Pre-Crisis counterpart, Corben is the beneficiary of Professor Vale's genius and is transformed into a cybernetic entity with a Kryptonite heart.[4]
  • Supergirl chooses the name Linda Lee as her civilian identity on Earth. Ironically, the name fits the double "L" naming convention common to many of the women in Superman's life.
